(54) Method and system for delivering a medical device to a selected position within a lumen


(57) Method and system for determining the location of a selected position within a lumen. The method comprises the procedures of registering a three-dimensional coordinate system with a two-dimensional coordinate system, the three-dimensional coordinate system being associated with a medical positioning system (MPS), said two-dimensional coordinate system being associated with a two-dimensional image acquisition device; selecting at least one point corresponding to said selected position on a first two-dimensional image of said lumen, and selecting at least another point, corresponding to said selected position on at least a second two-dimensional image, the respective viewing directions of said first two dimensional image and said at least second two-dimensional image are different from each other, each of said first and said at least second two-dimensional images is associated with a respective image plane in said three-dimensional coordinate system, each of said at least one point and said at least other point is associated with a respective location in the respective image plane associated with the respective image on which said at least one point and said at least another point were selected; determining the location of said selected position in said three-dimensional coordinate system according to the respective locations of said at least one point and said at least another point on the respective image planes thereof and according to said viewing directions of said first and said at least second two-dimensional images.
